Problems solved by technology

[0003] The existing hoisting mechanism of heavy equipment has the following characteristics: the use of motor control can realize a large range of plane movement and lifting process, but it cannot realize precise position control, and there is no way to realize the high-precision installation process of the main mirror chamber, and because the main mirror The special structure of the main mirror room, and the ordinary support structure cannot meet the requirements of a series of working conditions such as lifting, fixing, and positioning of the main mirror room. The primary mirror poses certain dangers

Abstract

The invention belongs to the technical field of optical instruments, and provides a high-precision adjustment device for a large-aperture main mirror cell. The high-precision adjustment device comprises a main frame assembly, the upper portion of the main frame assembly is provided with a lifting assembly and an adjusting assembly, an advance ball is arranged on the lifting assembly, and the advance ball is connected with the main mirror cell. The lifting assembly is used for bearing the main mirror cell, the adjusting assembly is provided with an adjusting screw, one end of the adjusting screw is connected with the main mirror cell, the adjusting screw is arranged in the radial direction of the main mirror cell, and the adjusting assembly is used for translation adjustment of the main mirror cell. The high-precision adjustment device can adjust the main mirror cell at multiple degrees of freedom at a high precision.

Description

technical field [0001] The invention belongs to the technical field of optical instruments, and in particular relates to a high-precision adjustment device for a large-diameter primary mirror chamber. Background technique [0002] In space detection and astronomical observation, in order to improve the observation resolution, it is necessary to increase the aperture of the photoelectric detection equipment. The mirror chamber also weighed heavily and was very expensive to build. Lifting, installing, and transporting the primary mirror together with the primary mirror chamber are all accompanied by great risks in the operation process. The main mirror chamber supporting the primary mirror, together with the complex support structure, needs to achieve high-precision positional movement control, including plane movement. And to successfully install it in the large telescope system, it is necessary to realize the high-precision adjustment function. Therefore, it is necessary t...
